DESCRIPTION
internally organized as 512 x 8. The X25040 features a
Serial Peripheral Interface (SPI) and software protocol,
allowing operation on a simple three-wire bus. The bus
signals are a clock input (SCK) plus separate data in
(SI) and data out (SO) lines. Access to the device is
controlled through a chip select (CS) input, allowing
any number of devices to share the same bus.
The X25040 also features two additional inputs that
provide the end user with added flexibility. By asserting
the HOLD input, the X25040 will ignore transitions on
its inputs, thus allowing the host to service higher pri-
ority interrupts. The WP input can be used as a hard-
wire input to the X25040, disabling all write attempts,
thus providing a mechanism for limiting end user capa-
bility of altering the memory.
The X25040 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 1,000,000
cycles per byte and a minimum data retention of 100
years.
